The agreement comes after Brown's death led to massive protests in Ferguson, helping give rise to the Black Lives Matter movement and its protests against racial disparities in the criminal justice system and police use of force.

Justice Department and Ferguson negotiators tentatively agreed to policing reforms in January. But the agreement stalled lathe Ferguson City Council raised concerns about costs. But the Justice Department threatened a lawsuit, and told Ferguson officials that their cost concerns were inflated, pushing city officials to finally accept the agreement."
